Sorting out the Red Sea

I'm working on the TAVO Index materials and came across the Red Sea. I followed the referrals and noticed it was getting confusing, so I made a diagram. then I made one for Pleiades too. I've attached them. Note that the TAVO Index is not consistent about the referral links, contrary to what I had hoped, e.g., "Rotes Meer" and "al-Baḥr al-Aḥmar" are the same but not linked. On the Pleiades side, the "Arabicus Sinus/Erythr(ae)um/Rubrum Mare" Place stands out, even more when you look at the accompanying note: "large section of the Indian Ocean, including the Persian Gulf and Red Sea." The "Erythraeum Mare," for instance, is both equated with the "Rubrum Mare" (Red Sea) and the "Persicus Sinus" (Persian Gulf). TAVO keeps anything Eritrean solidly on the Red Sea side at least.

This may be an extreme case but contradictory/overlapping definitions w/o time restrictions do occur. I'm not sure what to do with these.

It would be helpful to work up a robust descriptive and modeling solution for the Red Sea case and offer this up as an example for similarly problematic feature/name associations.
